 ### 1. **On the Target Server Running MySQL Applications:**
 
 Configure the route commands to direct response packets to the assistant server. For example, assuming `10.110.12.18` is the IP address of the assistant server and `10.110.12.15` is the MySQL client IP address, use the following route command to direct all responses from `10.110.12.15` to the assistant server:

 `tcpcopy` captures MySQL packets (assuming MySQL listens on port 3306) on the current server, modifies them as needed, and forwards them to port 3306 on `10.110.12.17` (the target MySQL server). It also connects to `10.110.12.18` to request that `intercept` forwards the response packets to it.

 ## Note
+
 1. User Accounts and Privileges: Both MySQL instances on the target and online servers must have identical user accounts and privileges, though passwords can differ.
 2. Session Replay: Only complete sessions can be replayed.
 3. OpenSSL Support: OpenSSL 1.1.0+ is not currently supported.
 4. Password Plugin Compatibility: MySQL 8.0’s caching_sha2_password is not supported. To test MySQL 8.0 using MySQL 5.7 production flows, use mysql_native_password and ensure that all users involved in the test are configured with the mysql_native_password plugin.
